One of the most alarming experiences for a new Minoxidil user is noticing increased hair shedding in the first month. The natural instinct is to stop the medication immediately. Dr. John Watts — dermatologist, trichologist and hair transplant surgeon in Hyderabad with over 2,000 successful procedures — explains why stopping at this point is actually the wrong move.
Why does Minoxidil cause hair shedding at first?
Hair shedding in the early weeks of Minoxidil use is a well-documented and common side effect. Minoxidil shifts hair follicles from the telogen (resting) phase into the active shedding phase — and this transition causes existing hairs to fall out before new ones grow in their place.
“This shedding is typically temporary, and new hair growth should occur again. There is no need to stop using it or getting scared,” explained Dr. John Watts.
Is the shed hair gone forever?
For most patients, no. The shed hair will grow back as the cycle resets and new growth begins. However, if the hair shedding is driven by DHT, the regrowing hair may come back thinner and smaller over time through miniaturisation.
“It is crucial that one continues to use Minoxidil as directed for at least 6–9 months to see good results. Not only will it halt the process of miniaturisation of hair, but one can stop the hair thinning process. The hair will also have proper length and size,” explained Dr. John Watts.
Other causes of early hair shedding
“Besides Minoxidil use at the initial stage, hair shedding can occur due to the onset of baldness, nutritional or vitamin deficiencies, or stress. In these cases, hair loss is not permanent and may grow back naturally once the underlying cause is addressed,” Dr. Watts pointed out.
The bottom line
Stopping Minoxidil the moment you see shedding is one of the most common reasons the medication fails. The medication needs 6–9 months of consistent use to demonstrate its full effect. Shedding in the first month is expected, temporary and not a reason to stop.

Frequently asked questions
Is hair shedding after starting Minoxidil normal?
Yes. Dr. John Watts explains that Minoxidil pushes follicles from the resting phase into the shedding phase before new growth begins. It is a common and temporary side effect.
Will the shed hair grow back after Minoxidil shedding?
In most cases, yes. New growth follows the shedding phase. However, if the loss is DHT-driven, hair may regrow thinner over time unless Minoxidil is continued to halt miniaturisation.
How long should you use Minoxidil before judging results?
Dr. Watts recommends continuing Minoxidil for at least 6–9 months consistently before evaluating whether it is working.
